Short answer: the Doss Soundbox Pro on value, the Ultimate Ears Megaboom 4 for IP67 and floating, though neither ranks well in its class. The Doss costs $49.99 against $200 and packs 20W, IPX6, 20-hour battery life, an extra bass button and dual woofer drivers, but it has barely any bass. The Megaboom 4 is IP67 rated, floats and finally uses USB-C charging, yet it distorts a lot at higher volumes. Both are rated below 3.0/5 among the 151 medium speakers; for better sound, the Earfun Uboom L ranks #1 at $49.79.
Buy the Doss Soundbox Pro. Both are rated the same for sound quality, and it costs $150.01 less than the Ultimate Ears Megaboom 4.
